Step away from the Netflix and get yourself to a screening of Alfred Hitchcock’s 1927 “The Lodger: A Story of the London Fog,” presented by the Independent Film Society of Colorado.

The 90-minute, silent, black and white film, based on Marie Belloc Lowndes’ bestselling novel “The Lodger,” was Hitchcock’s first thriller and first critical and commercial success. It’s loosely based on the Jack the Ripper murders. Ralph Giordano, the executive director of Peak Film Forum, will give a 15-minute talk after the film.

There are two showtimes: 4 or 6:30 p.m. Friday, at Cottonwood Center for the Arts, 427 E. Colorado Ave., $15; ifsoc-cottonwood.eventive.org/welcome.
